The influence of recycled concrete aggregate on the properties of concrete
MATEC Web of Conferences, 2018 Use of Recycled Coarse Aggregate (RCA) in concrete can be described in terms of environmental protection and economy. This paper deals with the mechanical properties of concrete compressive strength, splitting tensile strength, modulus of elasticity, and

Recycled powder as filler admixture in cementitious systems : production and characterization [PDF]
, 2016 In concrete production, aggregate represents almost 75% of the materials used. The exploitation of natural sources for this purpose also causes an environmental impact, while deposition of wastes from construction industry pollutes soil and water.

Influence of ageing on the properties of bitumen from asphalt mixtures with recycled concrete aggregates [PDF]
, 2015 The reuse of recycled concrete aggregates in new hot-mix asphalt can be a more sustainable method of production, but these mixtures may need a heat treatment before compaction to improve their water sensitivity performance.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural biology of ferritin nanocages
FEBS Letters, EarlyView.Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

The use of recycled aggregate has become a necessity for some countries due to the environmental and economical burden of dumping waste material. Recycled aggregate can be used in many ways, most commonly as base in road construction. The use of recycled aggregate in new concrete has been investigated and is currently being used for applications ...

FEBS Letters, EarlyView.In this study, we found that human cervical‐derived adipocytes maintain intracellular iron level by regulating the expression of iron transport‐related proteins during adrenergic stimulation. Melanotransferrin is predicted to interact with transferrin receptor 1 based on in silico analysis.

The characterization of recycled concrete aggregate as filter in removal of phosphorus [PDF]
, 2020 Phosphorus (P) is one of the key nutrients that lead to eutrophication problem in surface water. However, the existing conventional wastewater treatment system to remove phosphorus is expensive and require a complex process. Therefore, a system using low

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.
